The instructions leave me a bit confused about how to connect the tuner to a long wire (actually a dipole fed by twin-lead, I will twist the leads together). The tuner is well-grounded to the rig, which is well-grounded to earth ground (via the wing nut post)

To which post do I connect the long wire? The upper left or upper right (looking at the back of tuner)

Also, can someone confirm that the post marked "Wire" on the bottom (next to the ground wing nut) is left disconnected when operating as a long wire (it's connected now with the twin lead)

Connect your "wire" (shorted feeders) to the lower left terminal labeled "wire." Be sure there is no jumper connected to the terminal marked " wire." I normally leave a jumper between the two terminals labeled "balanced line." When I switch from a single wire to a balanced feed I connect the jumper from the upper left "balanced feed" terminal to the lower left "wire" terminal

I did have a follow-up question - will the tuner still tune when oeprating through an antenna the wire post? I gotta assume that the antenna won't just tune up on 160. Gonna need some help getting all the way to 160...

If the tuner will not match a single wire on 160 meters a series inductor can be added at the tuner. I use a large diameter PVC pipe coupler. Wind #14 THHN (house wire) close wound on it and you will have a nice coil having a Q around 300. The large pipe coupler sets nicely on the desk and looks good.
